The invention is'- applicable to all of the machines which contain a rotary platen'. t is shown embodied .in mechanism which is especiallyuseful-*in doing lbilling-work, but it may be used' for plained.

several puiitilosesy as will `be hereinafter exlaten wliich are different from the ordinaryy e particular.meenam'sin'` illustrated in Figs. 1 et seg. 'to 5, inclusive, of the drawings will first be described.

The truckl and platen frame 2 are well known parts of the Remington machine, the truck being mounted on a cross rod 3 on which it is supported by means of rollers or wheels 4 having bearings on the truck. The platen frame is hinged to the truck by links 5 formed on or fixed to a rock shaft 6 and pivoted to the rear of the platen frame at 7, the rock shaft having bearings at its ends on the ends of the truck 1. On the ends of the carriage are projections 8 which extend between stops 9 and 10 formed on the truck at each end, these stops and projections serving.

to limit the movement of theplaten, when it is shifted to provide for rinting upper and lower case characters. n the front of the carriage frame is mounted a grooved roller '11 which normally rests on a shift-rod 12,

this rod being movable on arms 13 toward and from the'front of the machine for the pu ose of shifting the platen. On an arm 14 ormed on the rightlend of the platen frame is pivoted a line spacing lever 15 on.

which is mounted aline spacing pawl 16. A spring 17, coiled about the pivot of the lever 15 and bearing at its endslon pins 1S and 19 fixed in the lever and platen frame'respectively, tends position. A stop having faces 21, 22 and 23 is pivoted by a pin 24 on an arm 25 formed on the platen frame, this stop b earin against the surface 26 on the pawls 16 an serving to limit the forward movement of-thepawl.;

and on lthe truck is mountedga the mechanism thus far lescrihed be found in the well known Remingtonmas;` chine, and its operation will b e' understood.

The platen 81 is supported .at its left Paper Support 30..- A1153v 105` by a head 32 having on it a tubular hub 33, and by a short rod 34 extending through the hub 33 and the left end of the platen frame, the hub being aflixed to the shaft 34'by a set screw 35. The head 32is fastened' tothe end of the platen by screws 36. On the shaft 34 outside of the platen frame is a finger wheel 37-having on it a hub 38 which fits on the' shaft 34 and is affixed thereto by a set screw 39. At the right end of the laten is a line s acing wheel 40 having a ho low hub 41 whic fits in the 'right end of the platen frame 2 and forms a journal for the line spacing wheel and platen. On the inner face of the line spacing wheel is formed a tubular hub 42, on which rings 4 3 anrL44 are fastened by screws 454and 46respectively, which pass through the rings into the hub 42, these rings formingat their inner edges a portion of a ball race.l A ring 47 is fastened in the platenby screws 48 vand in this ring is a groove which forms the rest of the ball race mentioned, and th ball race contains a set of balls 49. The parts just described form a ball bearing for the right end of the platen, and the laten may be turned in either direction on t is bearingV when the line spacing .wheel is at rest.

Within the platen is ascrew 50 which is shown in the form of a spirally grooved cylinder, but which might have a spiral rib formed on it instead of thegroove, and this screw is affixed to a shaft 51 which extends through the line spacing wheel 40 and the right end ofthe laten frame, passing through the hubs 41 an 42 of the line spaclng wheel,

and on the outer end of thjs'shaft is a finger The axis of the screw 50 and thatv of the shaft 51 coincide with the axis of the Wheel 52.

platen. In the hub 53 of the finger Wheel 52 is a set screw 54, by means of which the finger wheel may be fastened to the shaft 51,

along which the linger wheel is adjustable. This shaft has in it a groove 55, 'and in the line spacing wheel is a feather 56 which is fast in the wheel and extends into the groove 55. On the front side of this shaft Jare vvstraight marks or cuts and the numerals- {(07)} 6177, ((21), H37), (C47) llfformng a scale. A collar 57 is mounted on the shaft 51 within the platen and is attached to the shaft by a set screw 58 so that the position o f the collar may be changed if deslred. The screw 50 passes through and engages with a block or counterpart 59, which 1s secured in the platen about midway between its ends by screws 60. A spring-pressed roller or detent 61, thespring 62 of which is fastened at its rear end to the platen frame, normally engages the line spacing wheel 40 and tends to prevent it from turning on its axis. The

`construction described is such that when the line spacing wheel is held by the detent, ,and the shaft 51 and the screw`50, which it will be understood are axially movable, areA drawn 'line s pacin -wheeL -so adjuste on 'the shaft 51 that the left end toward the right by the hand of the operator' grasping the finger wheel 52, the platen will..

be rotated vbyfthe action of the screw on its counterpart 59, the shaft 51 being revented from turning on its axis by the flather '56 tting'in the groove 55. The screw 50 being a right-hand screw the platen will obviouslyA be rotated forwardly when the shaft and screw are drawn toward the right, and the platen may be actuated in this direction as escribed until 'the collar 57 is brought into I contact with the inner face of the line spacin wheel 40, when the platen will be arreste By pushing the shaft and screw inward the platen may be rotated in the opposite direction Orbackwardly until the hub 53 ofthe' finger wheel 52 meets the platen frame 2, orA

theouter end of the hub 41 of the line spacing wheel. The collar or-sto 57 is so located on vthe shaft 51 that when t e rightface of the collar is in contact with the inner face of the line spacing wheel the scale mark 0 on the shaft is even with the outer face' of 'the platen frame. The scale marks shown are so arranged that if the mark O is even with the right face of the platen frame and the shaft the surface of the p aten will be moved backward one inch when the scale mark 1 is even with the right face of the platen frame, and two, three, four or ve inches respec- 4tively when thescale mark 2, 3, 4

5 is even with the rignt .face pf the platen frame. The paper is fed into the machlne by the co-action of the platen with the usual feedrolls 63, shown in dotted lines in Fig. 1,

vand is pressed against the front of the platen by rolls 64 as it passes through the machine.

If, therefore, bill-sheets or letter-sheets are to be used on whichit isdesired to write the first line when the sheets have been fed into and screw are then pushedinward, a point on they machine three inches, for example, the` shaft 51 and screw 50 are first drawn outward until the scale-numeral 3 is even with the right face of the platen frame,- and thena sheet i's inserted in thezmachine and the shaft and screw are further drawn outward until the stop 57 arrests the laten. By this means the sheet is fed into t e machine the desired distance. After entries have been made on a sheet the platen may be rotated backwardly the desired distance to .provide for inserting another sheet, by push' mg 'inward the shaft 51 and screw 50 until I the scale numeral 3 is even'With-the .ri ht face ofl the platen, frame. sheet maybe inserted in the machine and fed Then anot erv i forward the desired distance by pulling out- Ward the shaftand screw until the forward movement of the platen arrested by the action of the stop 57 `on the inner face of the If theinger wheel 52 is of the hub 53 registers withl the scale mark screw arepushed inward as independently of the A described, the backward movement of the laten will be terminated by the action of t ie hub or stop 53 against the platen frame, when theplaten hasbeen turne to the desired extent.

As the platen is rotated in either direction actuating the shaft 51 the right end of the platen turns on the ball bearing which has been described above and which includes the balls 49 and the platen therefore rotated line spacing wheel. When, the line spacing lever 15 is actuated the p'awl 16 engages a tooth of the line spacing-heel 40 and this wheel is turned, the shaft 51 being turned with it through the action on the shaft of the feather 56, and the platen is also turned .through the action of i' the screw 5() on its counterpart .59 fixed in the platen. When the finger wheel 87 is turned, the platen, the screw 50,. shaft 51, and line` spacing-wheel 40 are turned together, motion being im arted to the screw by the action thereon o its counterpart 59, and from the screw to the shaft and linespacing wheel.` The platen,l line spacing wheel, shaft and screw may also be rotated in. either direction. by turningthe finger wheel 52, motion then being imparted tothe platen by the action of the screw on its coun- It will be understood that. theterpart 59.

Theball. bearmg at the right end of the platen is also- :the same as the f described above. on a shaft 66 which forward when the screw and shaft are pushed inward. Therefore when a sheet of paper has been fed into the machine and entries are being made on the paper the finger wheel 67 is close to the right end of the. platen frame, instead of at a considerabledistance from it as is the finger Wheel 52 ofthe construction shown in Fig.. 2 under similar conditions. The shaft 66 may be drawn outward until the right end of the screw 65 meets the inner face of the line space wheel, and .i istherefore not necessary to,lput on thisl shaft' a stop collar like the collar 57, the screw itself performing the function of such a stop. The action of this construction will'be understood, it is believed, scription of the construction and operation of the'mechanism shown in Figs. 1 to 5.

The invention may also be utilized for imparting variable line space movements to the platen as well as for use in doing condensed billing. By actuating the screw the platen may be rotated any fractional part of a line space or of several line spaces, while the line-spacingwheel is at rest, and thereafter the platen may be actuated in the usual way by operating the line spacing lever. The invention may also be utilized to facilitate making corrections in writing done on visible-writing machines, such, for example, as a Monarch machine, of which parts are shown .in Fig. 8 of the drawings.v

The platen 71 of this machine is supported in a`fram'e 72 mounted on balls/ 73,'which travel in guides 74 aixed to` standards 75 which are fast on the top plate 76 of the machine frame. The type bars are pivotally mounted on a type bar segment 77, each type bar 78 being arranged to swing on its pivotal axis 79 so that each of the type 80 on 4the bar may be made to act against the front' of the platen at the printing point 81.-. The curved dotted line extending from the' front type on the type bar shown to the platen indicates the path in which the type type bar is actuated to print With'thistype.

The type bars normally rest 'atftheir front ends on a'type bar rest 82. Thefcommon scale bar 83 is shown in cr'ossisection and aper feed rollers 84 and pressurerollers 85..

are indicated in dotted lines.4 'A heavy doti ted line 86 rr'esents a Asheet-of'paper-inthe machine. in writing done onthis machine vit is desiry able to turn the platen forward, supposingl the printed letter is either on a horizonta to the line containing lthe printing point, so

letter may be written. From .v 139 that the proper the foregoing description ofthe invention itl en a--correction is-t'o'be made will be seen that it may be applied to this visible writing machine, and that the adjustable finger wheel may be s o arran ed. on the axially movable shaft as-to enab e the platen to be rotated for the purpose just de scribed by actuating the finger wheel, and to cause the platen to be arrested by one stop when it has been rotated forward the desired distance, and to'be arrested by the other stop when it has been rotated back.- ward so that the space to be filled is on a horizontal line pa/ssing through the printing oint. I p The invention may be embodied in mechanism differing in various respects from that shown and particularly described herein, especially in details of construction and arrangement of parts, and it is therefore intended to claim the invention as broadly as it may be proper to claim -it in view of the prior state of the art.
